Title: Improvements in or modifications of electrolytic production of tungsten or molybdenum
IPC: C25C3/34
Filed: 1964-05-28
Abstract: In the continuous production of W or Mo from its oxide by electrolysis in a fused bath of at least one alkaline earth metal halide and a mixture of the oxides of at least one alkaline earth metal and of the product metal to cathodically deposit pure ductile and crystalline metal, the product metal oxide is replenished by addition as it is consumed and accumulation of surplus alkaline earth metal oxide is prevented by passing chlorine gas through the melt to convert the surplus oxide to the chloride.  Typically the alkaline earth metal compounds used are those of Ca and preferably the baths contain 0.1 to 15% free CaO. In place of the mixture of alkaline earth and product metal oxides, there may be used the ores scheelite and powellite for W and Mo respectively, while for Mo production, the crude Ca Mo O4 obtained commercially by roasting MoS2 may be used. The temperature of the bath is 1000 DEG C. the applied voltage is 2.2 to 2.4 V, the cathode current density is 3.5 to 4.1 amps/in2, and chlorine is blown through the bath via a tube of quartz or silimanite (aluminium silicate).  The cathode deposit is agitated in water to dissolve out adhering salt and washed in hydrochloric acid.

Title: Method of controlling microorganisms in food products
Inventor: FEHR ISAAC NEWTON
IPC: A23L3/01
Filed: 1966-05-23
Abstract: The control of microorganisms in a food or beverage product is effected by packaging the product in a dielectric container and exposing the packaged product to a field of alternating electromagnetic wave energy having a frequency of 20-40 megacycles per second at an intensity of 500-3,000 volts per centimetre for a sufficient length of time to attentuate the microorganisms in the product.  Sterilization is thus effected with little or no heat production and can be applied to raw or precooked foods prior to, or after freezing.  The treatment of fruit flavoured beverages, bread and biscuits is exemplified. Other materials specified are milk, wine, beer, carbonated beverages, frozen eggs, spices, meats and dehydrated soups.

Title: Improvements in the manufacture and production, from dolomite, of magnesia deficientin lime and calcium nitrate
IPC: C01F5/20
Filed: 1933-08-17
Abstract: Magnesia poor in lime and a concentrated calcium nitrate solution are obtained by precipitating a solution of dolomite in nitric acid by means of lime or calcined dolomite in the presence of ammonia or an ammonium salt such as the nitrate.  The ammoniacal calcium nitrate solution obtained may be evaporated to recover ammonia for re-use and solid calcium nitrate, or be neutralised with nitric acid to obtain a mixture of calcium and ammonium nitrates which may be used as a fertiliser.  Liquid, gaseous, or aqueous ammonia may be used in the process, and ferric hydroxide deposited on first adding ammonia may be filtered off to avoid contamination of the magnesia.  Milk of lime or milk of dolomite may be used for the precipitation, but the use of the reagent in lump or ground form is preferred as this leads to a more concentrated calcium nitrate solution.

Abstract: 1,108,784. Protective arrangements. LICENTIA PATENT-VERWALTUNGS G.m.b.H. 31 May, 1965, No. 23110/65. Heading H2H. Apparatus for limiting the current in an interconnecting circuit between two A.C. networks comprises a series RC circuit which resonates under normal current conditions but which departs from resonance, thereby increasing the impedance of the circuit, when the current tends to rise above a given value. Two networks 1, 2 are interconnected by a circuit including a transformer coupled capacitor C and inductor RL normally resonant, the capacitor having a pair of reverse parallel connected silicon controlled rectifiers R1, R2 in shunt therewith. When an excessive current flows in the circuit the rectifiers are made conductive by means of a current transformer CT to short circuit the capacitor. Alternatively the rectifiers may be connected in shunt with the inductor. In another embodiment the capacitor is in series with an inductive element having two inductors in parallel one of which has an air or air-gapped core whilst the other has a core of high permeability material, the resistance of the combination being current responsive.
